BCP51-16T-QF

Overview

The BCP51-16T-QF is a PNP power bipolar junction transistor manufactured by Nexperia. It utilizes silicon technology and is housed in an SOT-89-3 surface-mount package. The device supports a maximum collector current of 1 A and withstands a collector-emitter voltage of 45 V. Key electrical parameters include a collector-base voltage of 45 V, an emitter-base voltage of 5 V, and a saturation voltage of 500 mV. Power dissipation is rated at 500 mW with a gain-bandwidth product of 140 MHz. The component operates within a temperature range of -55°C to +150°C and features a DC current gain (hFE) ranging from 63 to 250.

Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm it denotes the correct tape-and-reel packaging variant for this part number. Ensure the selected component matches the required AEC-Q101 qualification status if used in automotive applications. Cross-reference the datasheet revision date to guarantee parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when a PNP transistor with 1 A continuous current handling and 45 V voltage rating is required in a compact SMD form factor. The SOT-89 package offers higher power dissipation than standard small-signal packages. Consider the specific hFE bin required for the application, as gain varies between minimum and maximum limits defined in the datasheet specifications.

Part Context

This part belongs to the BCX51/BCP51 family of power bipolar transistors designed for general-purpose switching and amplification. The QF suffix typically indicates a specific reel packaging configuration. It serves as the PNP complement to NPN variants within the same series, sharing similar thermal and electrical characteristics while differing in polarity.

Replacement Considerations

The BCX51T is the direct NPN complement within the same package and specification family. For equivalent PNP functionality, verify compatibility with the BCX51-10T or BCX51-16T depending on the required current gain binning. Ensure any substitute maintains the SOT-89 footprint and AEC-Q101 qualification if automotive compliance is mandatory.
